Environmental Absolute Reliability Thermal Shock Test Chamber
Thermal shock chamber is a chamber which use method of
environmental testing that subjects a product to alternating
extremes of high and low temperatures. The application of rapid
temperature cycling is the most effective manner of creating
premature failures of products in the production phase. We can
simulate all natural temperatures which, when considering the
fields of aviation and aerospace, range between -80 °C and +220 °C.
It is used to test the capability of material structure or
composite material to withstand the continuous environmental
changes between extremely high temperature and low temperature
during a short period.
1) Test samples don't move. Thermal shork chamber in each zone for
peak demand of heating and cooling.
2) Horizontal airflow design assures uniform results
3) Extremely compact systems with a vertically sliding door for added
4) Utilizes the latest refrigeration technology: electronic expansion
valve and high-tech compressor. Provides extra thermal energy to
efficiently meet the MIL-STD 883 requirements.
5) Temperature recorder provides 24 hour part temperature recording
as the load travels from zone to zone.
6) Using touch-control graph control as operation interface, easy to
7) The system can be used for automatic Circulation Shock or manual
selective shock, capable of setting two zones or three zones shocks
as well as cold and thermal shock start-up.
8) Custom-made and optional accessories available.

There are three chambers used to perform thermal shock testing,
high-temperature chamber, low-temperature chamber and test chamber.
Sample is placed in the test chamber, more extreme temperature than
test temperature can be set in high-temperature chamber and
low-temperature chamber. When doing low temperature testing, cold
chamber door open, and low-temperature chamber working together
with test chamber.
When converted into high-temperature test, cold chamber door
closed, hot chamber door are opened, and test chamber working
together with high-temperature chamber. Conversion of mechanical
action (transferring from high temperature to low temperature or
low temperature to high temperature) can be completed in less than
1second, and the temperature can be quickly stabilized.
During the whole test, test sample is no need to be moved, and
without any human intervention.
